I’ve been to the catacombs of Rome. Not for the claustrophobic! But I must say the figure who is identified as a woman looks like a man to me.
I certainly can't tell from the face or figure, but 1 Corinthians 11 says that women are to keep their heads covered (and men, their heads uncovered) in the Christian church. But how one can infer she is 'leading' anything is pure speculation out of the mind of the beholder. Perhaps she is praising, prophesying, or just breaking out in 'jazz hands'.
That’s a man, baby.
